1 Claim.

The present invention relates particularly to means for pumping liquid to a sewer or other discharge system from the waste outlets of sinks, basins, water-closets or other devices disposed l"5 upon a lower level.

It is one object of the invention to provide means of the character indicated wherein an electric motor, a pump, and a control for the motor rendered operative or inoperative by the action "T of the pump through the passage of materialr therethrough, together with such working parts as may be connected thereto, are so arranged as to secure synchronous action between the same at all times, and at the same time simplify the ""15 construction and operation of the several members.

It is also an object to provide an assembly of the character indicated that will be small and compact. light and portable, economical to manufacture, of few parts, simple in form and construction, strong, durable, and highly efficient in its practical application.

The drawing is a longitudinal side elevation-of an assembly embodying my invention, partly broken away, and with its enclosing case in section.

In the embodiment of the invention as herein disclosed I show at 1 a small oblong case with a removable top 2.

Disposed within the case and at one end there- 30 of is an electric motor 3 bolted to its bottom as at 4, the drive shaft of the motor being shown at 5.

Disposed substantially midway between the said motor and the other end of the case is a small centrifugal pump 6 supported upon a bracket 8 35 which is in turn mounted upon the bottom of case l with the axis of rota-tion of the pump in alignment with the axis of rotation of the motor shaft 5, the drive shaft of the pump being shown at 9.

The shafts and 9 are Vspaced a distance apart and connected by a short section of rubber pipe 10 secured thereto by means of clamps as 11-11, this pipe section forming a driving connection between the two elements and at the same time eiectually insulating the same against the pas-l (Cl. 10S-87) Mounted on the outer end of pipe 15 is aV receptacle 17, this receptacle communicating with the pipe 15 and extending a distance above the level thereof as shown. An intake pipe 13 enters the case from a sink or other `device and 60 discharges into the receptacle 17 as at 19 a distance above the level of the pipe 15. In the receptacle is disposed a iloat 20 having a stem 21 passing upwardly through a bearing 22 and through the opening 23 in the top of the recep- 65 tacle, the stem having a rubber gasket 24 mounted thereon to engage the top of the receptacle when the stem is pushed upwardly, and serving to elfectually prevent leakage at this point.

Upon a block of electricity insulating material 70 I 25 mounted on the top 26 of the receptacle is a pin 27 connected to the motor 3 by a Wire 23, and forming one side of a switch. The other side of the switch is formed by a pin 29 mounted on the block 25 and having a bar as 30 pivotally 75 mounted thereon as at 31 and swingable into contact with the pin 27. On bar is a block 32 of insulating material which normally overbalances the bar 30 and breaks its contact with pin 27, but which may be engaged by stem 21 80 to effect such a contact. The pin 29 is connected by wire 33 to motor 3 through the terminals 34 when they are inserted in an electrical circuit not shown,

Assuming the device to be connected up to anelectrical circuit through wires 23 and 33, and some utility is drained to discharge water into the receptacle 17, its action is as follows.

The water will ow into receptacle 17 with a rush, and on account of its small size will completely fill the same. The entrance of the water will actuate the float to push the stem 21 upwardly thereby sealing the opening 23 with the gasket 24, and at the same time pushing the bar '30 into contact with pin 27 and closing the cir- 95 cuit including the motor to operate the same. The operation of the motor 3 will, of course, drive the pump 6 which operates to pump the liquid from the receptacle 17 and discharge the same through the pipe 13 and the check valve 14. 100 When the liquid has been pumped out of the receptacle 17 suciently to permit the float to dro-p, the switch 30-27 is opened automatically and the motor 3 and pump 6 stopped.

The result of this particular method of as- V105 sembly is that a very small receptacle 17 may be used, since its float is immediately over the longitudinal axis of the inlet to the pump. A very small pump may be used and its suction controlled by valve 16. The connection at l0 forms \110 A device of the character described comprisi ing, the combination of a closed portable a pair of spaced brackets mounted within the lsame and on the bottom thereof, an electric motorv mounted on one bracket, a centrifugal pump mounted on the other bracket in axial alignment with the motor, a check-valved outlet for the pump, a rubber pipe coupling flxedly connecting the motor and pump shafts, a valve controlled inlet pipe connected to the pump in axial alignment with the pump shaft, a receptacle mounted upon and supported by said inlet pipe and cornmunicating therewith, said receptacle having an iriletjpipe cnnnected thereto, a'oat mounted in the receptacle 'immediately above the "level of the pump axis, a normally open switch controlled .electrical circuit including said motor and including a normally open switchV disposed on said receptacle' and means actuated by the float to close the switch and render the device operative.
